Hello,
I have a 2003 Freightliner Business Class. The speedometer is out by about 40km/25mi/h. If I'm doing 110km it reads that I'm doing 70. Which in turn means that the odometer is out as well.
Any idea what this could be or how to fix it?
It's not a tire underiflated/bald thing.

Two choices. Speed sensor (doubtful, they usually just fail) . Speedometer Head. Turn the key on, without starting. Speedometer and tach should go to max and then return to zero. If not they are likely bad.

Wait a minute. If I read wrong correct me.
70 MPH times 1.6 = 112 KMH.
Are we looking at a speedometer reading metric?
I’m assuming you’re matching GPS speed to dash? -
Mine quit working about 6 months ago. Can't put miles on log sheets..... No biggie

When I turn the key on (without starting) all the gauges max out then return back to the rest position. As normal. It's when I start driving that they are out. I'm not sure how much out it is at the low end. But I know at the high end it's reading wrong.
As for what blairandgretchen said,
The truck is in miles as it was originally American;
The speedo needle points at 70km/h (or 40mi/h) when actually doing 70mi/h
The only thing that would make sense is that when I'm doing a road speed of 70mi. The gauge is at 70km/h. Rather than at 70mi. So maybe it is correct, just showing the wrong number.
I'm going to take it for a drive right away and see what it reads on the lower end.
